Dietary behavior, specifically a low-fat, high-fiber diet, plays a role in the primary prevention of chronic diseases including cancer.
A community-based randomized trial to assess the impact of a low-intensity, physician-endorsed, self-help dietary intervention that provided tailored dietary feedback, and was designed to promote improved fat and fiber behavior in a rural, low-education/low-literacy, partly minority population. The data were collected from 1999 to 2003.
SETTING/PARTICIPANTS: A total of 754 patients from three physician practices in rural Virginia completed a baseline telephone survey assessing dietary and psychosocial information, and were then randomly assigned to the intervention or control condition. Follow-up telephone evaluation was based on 522 participants at 1 month, 470 at 6 months, and 516 participants at 12 months.
A series of tailored feedback, followed by brief telephone counseling and theory-based nutritional education booklets, provided by staggered delivery to the home.
Dietary fat and fiber behavior, dietary intentions to change, self-efficacy for dietary change, and fat and fiber knowledge.
The intervention group demonstrated significant improvement in dietary fat and fiber behaviors and intentions to change fat and fiber intake (p <0.05) at 1, 6, and 12 months.
The Rural Physician Cancer Prevention Project provides an effective model for achieving public health-level dietary health behavior changes among a rural, minority, and low-literacy/low-education population.
饮食行为，特别是低脂、高纤维饮食，在包括癌症在内的慢性疾病的一级预防中发挥作用。
一项基于社区的随机试验，旨在评估一种低强度、医生认可的自助式饮食干预措施的效果。该干预措施提供个性化饮食反馈，旨在促进农村地区低教育水平/低识字率的部分少数民族人群改善脂肪和纤维摄入行为。数据收集时间为1999年至2003年。
地点/参与者：弗吉尼亚州农村地区三家医生诊所的754名患者完成了一项基线电话调查，评估饮食和心理社会信息，然后被随机分配到干预组或对照组。随访电话评估基于1个月时的522名参与者、6个月时的470名参与者和12个月时的516名参与者。
一系列个性化反馈，随后是简短的电话咨询和基于理论的营养教育手册，通过交错送达家庭的方式提供。
饮食中的脂肪和纤维摄入行为、改变饮食的意愿、饮食改变的自我效能感以及脂肪和纤维知识。
干预组在1个月、6个月和12个月时，饮食中的脂肪和纤维行为以及改变脂肪和纤维摄入的意愿有显著改善（p<0.05）。
农村医生癌症预防项目为在农村、少数民族以及低识字率/低教育水平人群中实现公共卫生层面的饮食健康行为改变提供了一个有效模式。
